I've always been a big fan of DaisyDisk — I used it just today to free up a whole bunch of space — but I thought I'd give FlameGraph a go. It helped me free up 2.2GB of totally valuable space (this is a 120GB MBP - brutal) with 2 clicks instead of the 6 it would have taken DaisyDisk.

DaisyDisk essentially shows the exact same info as FlameGraph — if you 'unwrap the wheel' it's exactly the same! — but the latter makes the excellent design decision to label many of the bigger directories on the graph, rather than just a single level in a key. Often, when you're looking for big directories, you're really looking for big unnecessary directories, and being able to see way ahead really helps.

I'm sure there are arguments as to whether it's the "best" representation, but I'd contend that it's the most intuitive.

It's probably the first OS X App where I bought licenses for the whole family; they all benefited from it.

Hey, thanks for this. Was using WinDirStat. This is really fast! Plus I like the minimalistic interface.

Thanks for the recommendation. faster than "space sniffer" as well.

YES! I really wish there were others that scanned the MFT. I don't think Wiztree is as flexible with visualizations.

That's misleading - TreeSize also works by scanning the MFT.

Sadly as a consequence of this, it can only report file size, not disk usage. If you have a lot of folders with NTFS compression enabled, Wiztree becomes almost useless.

I like it too but I've found it to be pretty buggy sometimes, especially if the contents of a folder change or the folder itself is deleted while you're viewing it, you get an endless stream of Delphi exceptions.
